[OpenAFS] slave volumes

[Klaas Hagemann]

Hi,

as far as i understood afs, i can create severeal read-only replicas of a
volume. How is the decision made, which of these replicas is taken?
We have a distributes WAN and want to avoid that the Client takes a volume
which is behind a very thin connection. For availability reasons all the
replicas should stay available but in an ideal situation only the volume
with the widest or fastest connection should be taken first.

Can someone explain me the algorithm used by OpenAFS?

Thanks,

Klaas
